Application filed August 25, 1922'. Serial N-o. I584,170.l

T0 all whom t may concern i Be it known that I, IVILLIML E, SEXTON,

a citizen of the Dominion `.of Canada, and

resident of Long Island City,in the borough and county of Queens, cityand State of New York, have invented certain new and useful-Improvements, in Scaffolding: Construction, of which the `following isaspecification.y

\'I`his invention relatesto scaffoldingconstructiomand its object is to-providemeans whereby the individual parts of a scaffold can "be:effectively .and ,securely connected, without requiring the use of anynails,

spikes or the like, and whereby these .partsV can just as readily bedisconnected when the scaffolding hasvserved its purpose.

The objects and advantages of my invention will appear fully from thedescription following hereinafter, and the novelty will vbe pointed outin the appended claims.

Without desiring to restrict myself to the exact details shown, I haveillustrated in the accompanying drawings a satisfactory example of myinvention. In these drawings,

` Fig. 1 is a perspective view of a portion of a scaffolding erectedaccording to my invention; Figs. 2 and 3 are a perspective view and aplan view respectively of a clamp for connecting two upright members;and Figs. 4 and 5 are similar views of ay clamp for connecting putlogsor ledgers to such upright members.

The scaffold illustrated in Fig. 1 comprising upright members 10, 10which over V lap as shown at11. These overlapping portions are connectedby preferably two clamps 12 each having an open end 13 facilitating theplacing of the clamp 12 over the upright members 10, 10. A clamp plate14 serves to close the open end 13 and to hold the upright members andthe clamp in place, this plate being screwed into firm contact with oneof the upright members 10, by screws 15 provided with suitable handlesand screwing through the metal of the clamp 12. Similar screws 16 areprovided to connect the clamp 12 securely with the other' upright member10', and prevent slipping of one upright member with respect to theother or of the two upright members with respect to the clamp.

At a suitable point of the upright member 10 (or 10") I connecttherewith anotherl clamp, 17, provided with'an open end 18/t'ofacilitate its being placed on the upright member, with which it is"connected rigidly .i

PATENT FFI'C by means ofscrews 19. 'Vhenrvthe clamp is A 'secured toth'e'upright member, the 'latterabuts against the shorttransversemembers 20 of the clamp. The'otherhorizontal members, 21, of theclampare of a length greater formed between theupright member andthe verticalmember'sf22 `ofV the clamp, which space serves forthe receptionof theove1^-- than thevmembers 2O,k so that a space 1s lapping ends ofledgerslr 23' extending hej-g, tween successive upright'members inla-'di-f rection yparallel tothe wall of the building. f

These vledgers are'pressed into firm Contact with the upright 'membersby meansfiof,

screws 24 screw-threaded into the clamp member 22, and a very rigidconnection between adjacent upright members is thus estab lished. 1

For ,the purpose of connecting the upright members lying in a planetransverse to the face of the building, I provide,

preferably at a point above a clamp 17, a

is maderigid by means of screws correspending to the screws 24 on t-heclamps 17. The scaffold is thus securely connected in a directiontransverse to the face of the building. Adjacent putlogs serve in theusual manner as 'supports kfor the floor boards 27 of the scaffold.

By my invention I have provided a very simple manner of putting togetherthe individual parts of a scaffold, resulting in a very strong and rigidconstruction. A particular advantage resides in the fact that, I Y

do away with the use of nailsor spikes altogether, thus not onlyfacilitating the dis- -connecting of the parts, but also preventingtheir being damaged by the removatof nails l or spikes or otherconnecting devices whichy are driven into the wood.

Various modifications may be made with@ out departing from the nature ofmy invern tion as set frth in the appended claims,

I claim: i

1. A clamp for scaolding comprising Complemenfel Usheped Sections. each132W- ing parallel legs and a cross-leg connecting said parallel legs atone end, Connecting members extending transversely to and betweenopposed parallel legsof lsaid sections at opposite ends thereof to iXthe sections in spaced relation said connecting members comprisingintegral parts of said'parallel leofsand screws mounted in and passingthrough some of said legs and having their inner ends adapted to bearagainst elements to be clampedtogether to thereby create out'n wardpressures" whereby said clamp is caused t0 exert its clamping function.

'2Av clamp forr` scaffolding comprising complemental U-'shaped isectionseach havingp'ar'allel legs and cross-legs connecting said parallel legsvat one end and comprising` integral parts thereof, connecting membersextending transversely 'to and between opposed parallel legs ofsaidsections at opposite 'ends thereof to fixl the sections in spacedrelation and clamping screws extending through the cross-legs of saidclamp and having their` inner ends arranged to bear against `elements tobeclamped together to thereby create outward pressures whereby saidKclampy is caused to exert its clamping function. i

3. A clamp for scaifolding comprising complemental U-shaped sectionseach having parallel'legs and a cross-leg connecting said parallel legsat one end2 connecting members extending transversely to and lbletweenopposed parallel legs of said sections at opposite ends thereof to fixthe sections in spaced relation7 and clamping screws eX- tending throughcertain of the parallel legs and through the connecting members, saidScrews havingtheir inner ends arranged to bear againstv elements to beclamped together'and thereby create outward pressures whereby said clampis caused to exertits clamping function.

In'testimony whereof, I have signed this specification.
